It is excellent, low temperature resistant cold -resistant that this cable has electric conductive property, resistant oil, environmental protection, advantage such as the current -carrying capacity is big, the tensile is wear -resisting, can frequently remove, application temperature grade height, shielding property are good.
Description
Technical field
This utility model relates to electric wire, particularly relates to a kind of Cold-proof oilproof being applicable to offshore drilling platform and controls cable.
Background technology
Along with expanding economy, offshore drilling platform Cold-proof oilproof controls cable, is widely used in the occasion such as ac rated voltage 450/750V and following offshore drilling platform oil production equipment signal monitoring, the control of wind-power electricity generation warp resistance instrument, electrical equipment connection connection.
Along with the high speed development of China's offshore oil exploitation, offshore platform Cold-proof oilproof controls the cable auxiliary products as offshore platform, will obtain quickly development.Offshore platform Cold-proof oilproof controls cable and is mainly used in the signal transmission of offshore platform control system, is the neural lifeblood of control system on offshore platform, and properly functioning for offshore platform plays an important role.Owing to offshore platform controls the particularity of cable and key, at present many offshore platform maker require to use cold-resistant, oil resistant, anticorrosion, Halogen product for the control system connecting line of critical component, in case control system can normally work under emergency rating, it is to avoid unnecessary loss.
The manufacture of the offshore platform control cable of China at present is also in the primary stage, technical merit and level of processing plus each cable producer domestic are uneven, and offshore platform cable is had higher requirement by International Maritime Organization, not only require that cable used by offshore platform has low cigarette, Halogen, flame-retarding characteristic, also there is the requirements such as cold-resistant, oil resistant, cause certain production difficulty to domestic manufacturer.
Summary of the invention
For solving problems of the prior art, the purpose of this utility model is to provide a kind of Cold-proof oilproof being applicable to offshore drilling platform to control cable, it is excellent, low temperature resistant cold-resistant that this cable has electric conductivity, and oil resistant, environmental protection, current-carrying capacity are big, tensile wear-resistant, can frequently move, use the advantages such as temperature grade height, advantages of good shielding performance.
This utility model solves technical problem and adopts the following technical scheme that a kind of Cold-proof oilproof being applicable to offshore drilling platform controls cable, soft copper conductor is synthesized including anaerobic tin plating soft copper skein silk, extrude irradiation ethylene propylene rubber insulation material on conductor constituting insulated wire cores is insulating barrier, more than three insulated wire cores are twisted into cable core, the outer overlapping wrapped double-layer polyester band of cable core is band, weave tin plating anaerobic soft copper silk outside band and form screen layer, be restrictive coating outside screen layer.
Described cable core includes seven insulated wire cores.
Described screen layer is that outside band, count is the tin plating anaerobic soft copper silk of 85%.
Described restrictive coating is to extrude 90 DEG C of thermoplastic environment-protecting polyurethane outside screen layer to be formed.
Beneficial effect
1, conductor uses anaerobic tin plating soft copper silk, and twisting pitch controls at 12-14 times, and fine pith adds the stability of conductor, and tin coating can effectively prevent the rubber insulation material corrosion to copper material.
2, insulation uses irradiation ethylene propylene rubber insulated, after cross-linking through electron beam irradiation, and the electric property raising such as cold-resistant, aging, the tension etc. of insulating mechanical performance and current-carrying capacity and short circuit temperature.The longtime running temperature of cable can bring up to 105 DEG C, 125 DEG C, 135 DEG C, even 150 DEG C.
3, screen layer uses tinned copper wire shielding, and count is up to 85%, and shielding rejection coefficient is excellent, and the anti-external world is effective, it is ensured that between line pair, signal does not interfere with each other, and distorted signals is little, it is ensured that signal transmission quality.
4, oversheath uses 90 DEG C of thermoplastic environment-protecting polyurethane halogen-free material, outer jacket is made still to keep higher mechanical strength and elongation at break in psychro-environment, and greasy dirt low temperature environment can play Cold-proof oilproof effect on production platform, improve the service life of cable.
5, sheath uses extrusion-type sheath, makes cable core gap extrude polyurethane jacket, makes cable core tight, outward appearance rounding, and during the use of cable, cable core is not easily shifted, reduces the friction between cable core, increases the life-span of cable.
Accompanying drawing explanation
